Description

Energy recovery system {ENERGY RECONVERY SYSTEM}

The present invention relates to a system for improving energy use efficiency by recovering energy that cannot be converted into power energy and reusing it as power energy.

Global warming and environmental changes are serious due to greenhouse gas emissions from combustion engines, and research on developing alternative energy, improving fuel efficiency, and reducing greenhouse gas is also in full swing due to the depletion of fossil fuels.

Exhaust gases from the engine contain large amounts of thermal energy, temperatures ranging from 100 ° C to 900 ° C, and also contain flow energy. Flow energy is partly used to generate the rotational energy that drives the turbine in the turboturbine, and thermal energy is mostly discarded. There is also the release of thermal energy by the cooling water. The technology of recovering such waste heat and regenerating it as electrical energy or recovering heat energy with a heat exchanger to generate steam and regenerating it as rotational energy has been applied. However, the technology of regenerating with electric energy produces power using thermoelectric element technology, but has a disadvantage of low cost and efficiency of thermoelectric element.

The technology of recovering thermal energy, generating steam, and regenerating it into power energy has presented mounting volume and cost problems.

The cooling area of the condenser is inevitably increased because the amount of cooling is not equal. Also, the fluid resistance of the air increases rapidly due to the increase of speed during cooling due to the inflow of external air caused by driving of the car, thereby reducing energy efficiency. It is difficult to collect or recover heat during the regeneration and recovery of the waste heat of the cooling water. In addition, the heat exchanger that has solved such a problem has a disadvantage in that it is difficult to increase the contact area between heterogeneous materials by using a pipe or a pipe, so that the volume is large and the efficiency is low compared to the size.

Second, as shown in Figures 15 and 16, the outdoor air inlet mechanism 45 is attached to the front of the front cover 46 for opening and closing at an angle to reduce the air resistance, and when the front is open, the rear is closed to the running speed Air intake is increased and air resistance is large, but when the front is closed, the rear is opened, which reduces air resistance and reduces the air inflow, so the air is sucked into the cooling fan to cool the coolant, condensate and air conditioner refrigerant. The front cover 46 is opened, and the cooling fans 39, 42, and 93 are also operated to maximize the cooling effect.

The control of the outdoor air inlet 45 is described with the following six examples.

 ① In the engine preheating step, the front cover 46 is closed to prevent the coolant temperature from being lowered by the outside air.

 ② When the fuel loss due to the inflow resistance of the air at low speed is less than the power to operate the fan to inject air, the front is opened and the rear is closed to cool air in by the running speed.

 ③ When the fuel loss due to the inflow resistance of the air is higher than the power to operate the fan by introducing the air at high speed, the front is closed and the rear is opened, and the cooling air is sucked in by the cooling fan.

④ When the temperature of the coolant rises above the standard value, open the front cover 46 and operate the coolant cooling fan to enable precise temperature control of the coolant. Also

⑤ The outdoor air inlet 45 is attached to the radiator, condenser and steam condenser separately to have precise temperature control of cooling water, condenser performance of condenser and condenser performance of air conditioner condenser.

Fourth, the radiator may be arranged several times or not adjacent to each other in the order of the cooling water cooling air passage, the cooling water passage, the condensate passage, and the cooling water passage as shown in FIGS. 1, 2, 3, 4, 17, 18, 19, 20, and 21. It is arranged several tens of times alternately and each circulates in a zigzag to exchange heat to cool the cooling water.The passage of gas such as cooling air has a wide space between the plates and the liquid passage has a narrow space between them. Depending on the size and the size of the passage hole, welded sealing is connected to the passage connecting bushings 6, 7, 8, and 9 as shown in FIG. 26 to optimize the flow resistance of the fluid, and as shown in FIG. The heat sink 5 having the same cross section is strongly fixed by welding between the plate and the plate so that it can withstand high pressure and heat conduction is high, condensate and cooling water in the condensate passage The heat exchange between the coolant in the furnace and the heat exchange between the cooling air and the coolant in the cooling water cooling air passages above and below the cooling water passage may be performed, thereby allowing the outdoor air inlet 45 and the cooling water cooling fan ( It is optimally controlled by 39), and the blown air cools the cooling water, or loses heat by heat exchange between the cooling water and the condensate, thereby cooling the cooling water and simultaneously heating the condensate to recover the waste heat of the engine cooling water. It has a structure that can be used. 1 and 17, the cooling water passage extends the circulation passage to the engine waste heat exchanger and installs a valve in the insulating layer between the cooling water passage of the engine waste heat exchanger and the cooling water passage of the radiator to provide the engine waste heat and power assist device ( 30) allows the heat exchange between the liquid and the coolant to be used to heat the coolant using engine waste heat until the engine heats up to a certain temperature, reducing the engine's uptime at low temperatures and extending engine life and fuel economy. Had the advantage to increase.

Fifth, the engine waste heat exchanger is arranged several times or tens of times alternately and zigzag so that the condensate passage and the exhaust gas passage are adjacent and do not meet as shown in FIGS. 1, 2, 3, 4, 17, 18, 19, 20, and 21. Heat exchange is performed to recover the engine waste heat to heat the condensate liquid, and the passage of gas, such as the exhaust gas passage, has a wide gap between the plates and the passage of the condensate liquid, Depending on the size and the size of the passage hole, a welded hermetically connected passageway bushing (6, 7, 8, 9) as shown in FIG. 26 optimizes the flow resistance of the fluid, as shown in FIG. The heat sink 5 having the same cross section is strongly fixed by welding between the plate and the plate so that it can withstand high pressure and heat conduction is high. The heat exchange between the exhaust gases in the gas passage can be performed to heat the condensed water to a temperature close to the vaporization temperature, so that the condensed water in the power assist device can be prepared to generate rotational energy due to rapid vaporization, thereby improving thermal efficiency. Had

In the first embodiment, as shown in FIGS. 1 and 17, the power assist device includes a spiral exhaust gas passage 72 within the power assist device through the exhaust gas inlet and exhaust gas 32 including the high-temperature flow energy combusted by the engine. 74, 76) to generate the rotational power and conducts the primary heat exchange by conducting heat to the wing.

The exhaust gas 32 at a lower temperature circulates zigzag in the engine waste heat exchanger, undergoes secondary heat exchange, and is discharged to the outside through a muffler. At this time, the exhaust gas loses flow energy and thermal energy and functions as a conventional muffler. The reduction of is possible.

The condensate heated near the vaporization temperature in the engine waste heat exchanger is supplied to the power assist device through the condensate pipe 31. At this time, a check valve 27 is built in to prevent the backflow of the internal pressure of the rotating body whose pressure is increased due to the rapid vaporization of the condensate supplied through the liquid inlet 59 of the case. The supplied high temperature condensate rapidly expands inside the steam passages 71, 73, and 75 of the rotating body heated to high temperature by exhaust gas to generate rotating power energy in the rotating body, and then passes through the steam outlet 58 to form a steam discharge pipe. Discharged to (69). At this time, the upper portion 66 and the lower portion 67 of the fixing body 50 are each equipped with a plurality of rings 57 for maintaining airtightness.

Repeat the expansion. These cycles continue to circulate and generate power energy.

Here, the temperature of the exhaust gas from the engine is close to 1000 ° C., so the heat exchanger for recovering the exhaust gas heat must have a high heat resistance temperature. However, the present invention is to maintain the inside of the power assist apparatus at a high temperature to accumulate the heat of the exhaust gas to achieve the same effect as the expansion stroke of the existing cylindrical engine, and when the liquid close to the vaporization temperature is injected, the rapid vaporization occurs An expansion stroke occurs inside the auxiliary device. At this time, the temperature of the exhaust gas is deprived of heat to lower the temperature so that the engine waste heat exchanger does not have to withstand the high temperature. In addition, the existing steam engine needs to generate and supply gas of high temperature and high pressure by a combustion method such as a cylinder type or a turbine type, and a compressor pump storage tank having a structure capable of withstanding high pressure is required, but the present invention is close to the vaporization temperature. It only needs to withstand the pressure when it is discharged from the engine room because it does not need to withstand the high pressure because it is heated only to the temperature and supplied at low pressure to increase the pressure by the expansion by rapid vaporization inside the engine room. It is easy to reduce production costs.

In the second embodiment, as shown in FIGS. 2 and 18, the exhaust gas in which the second heat exchange is performed in the first embodiment is installed in the lower part of the engine waste heat exchanger as shown in FIG. Even in winter, it is possible to quickly heat up the cooling water until it reaches a certain temperature, so it is not necessary to provide a combustion heater separately, and it can be used for heating the car interior, and heat exchange rate can increase the waste heat recovery rate of the exhaust gas. In addition, the device cost also has the advantage of maximizing fuel economy at a low cost because only a few plates need to be added.

In the third embodiment, as shown in FIGS. 3 and 19, the heat insulation layer is additionally installed between the radiator and the engine waste heat exchanger in the second embodiment, so that the high temperature heat of the exhaust gas is conducted to the coolant during the high temperature weather condition. A method for preventing this is provided.

In the fourth embodiment, an air conditioner condenser and an air conditioner condenser cooling fan are further installed on the condenser of the third embodiment to simplify the installation of the apparatus, and an air conditioner condenser is provided which takes up less space and reduces production costs.
